Answer:
both
Explanation:
Sudden floods forced Mesopotamians to create an organized agricultural system to help them with farming and growing crops. Mesopotamia was very dry, hot and had little rainfall. Egyptians also did this when the floods went down, bc it left thick rich mud which was excellent soil to plant seeds in after it had been ploughed. The ancient Egyptians could grow crops only in the mud left behind when the Nile flooded.
